  • Patent number: 10213319
    Abstract: CT images near the pelvis are obtained before surgery, and a three-dimensional model of a pelvis part is created on a computer. The virtual three-dimensional bone model is used to plan an installation position of a guide instrument etc., and a virtual three-dimensional surgical site model including the guide instrument is constructed. Subsequently, during surgery, the guide instrument is installed, and three-dimensional images of a surgical site are obtained, and a measured three-dimensional surgical site model including the guide instrument is obtained. The virtual three-dimensional surgical site model and the measured three-dimensional surgical site model are compared, and an error between an ideal installation position of the guide instrument and an actual installation position of the guide instrument is detected to guide the operator to reduce the error.

  • Patent number: 9868934
    Abstract: The present invention allows a TET1 protein to be more stably expressed in human pluripotent stem cells than in the past by, inter alia, substituting the second amino acid from the amino terminal of a TET1 protein with a different amino acid. Furthermore upon differentiation of said pluripotent stem cells, it is possible to quickly eliminate the expression of, inter alia, NANOG, which is an inhibitor of differentiation and promote the expression of factors related to differentiation by introducing a variant TET1 protein to a pluripotent stem cell. The present invention provides a method for manufacturing pluripotent stem cells with increased differentiation potential, and a substance that is useful to said method.
